I am using Premier Elements Organizer 13, my OS is Windows 10. I have suddenly quit getting thumbnails for my video files after importing. I have checked the settings under Edit>Preferences>Files... the box for automatically generating thumbnails is checked. This is a recent development. I have also removed the files from the catalog and re-imported them, same results. These are file types that I have imported many times using the current version and a previous version of this program. I have also uninstalled the program and reinstalled it with the same results.

One other thing, when I select the files to create a project, the thumbnails are present in the media selector for the project.

Thank you for responding to my problem, unfortunately, this did not correct my issue. Since this did not help, I renamed the file referred to in the KB again, then uninstalled the program and reinstalled it again. I did make sure that there was no thumbs5.cache file, hoping then that after re-installation, the program would regenerate the file. I am still seeing the hourglass icon for the thumbnails.
